meanwell.com website review

115 files are served with short cache lifetimes, so returning visitors download them again (2.3 MB).

About 281 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.8 s faster on a phone.

Your mobile performance score is 42. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

90 KiB could be saved by minifying JavaScript.

About 22 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

8 images could be 414 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Google Tag Manager costs a phone 164 ms of main-thread work and 322 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

7 third-party services load with your homepage (Google Tag Manager, leadinfo.net and Google Analytics and others), adding 382 KiB and 181 ms of main-thread time.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 200 ms).

7 KiB could be saved by minifying CSS.

1 long task block the main thread while loading, the longest for 104 ms. During a long task the page ignores taps.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Real visitors wait 5.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

For real visitors the layout shifts by 1.00 (75th percentile). Good is under 0.1.

Your largest element takes 13.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The layout shifts by 1 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The page becomes fully interactive after 14.4 s. Good is under 3.8 s.

Visually, the page fills in at 9.3 s (Speed Index). Good is under 3.4 s.

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.8 s for your server to start answering (75th percentile). Good is under 800 ms.

12 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 99 ms to 107 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.7 MB in 133 requests on a phone: images 1.9 MB (74), scripts 707 KiB (35) and stylesheets 53 KiB (12). Under 2 MB keeps phones on slow connections fast.

10 images (1.4 MB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.75 g of CO₂e: 90.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 buttons have no accessible name, so screen readers announce just “button”.

1 element use ARIA attributes their role does not allow, which confuses screen readers.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

ARIA attributes must conform to valid values: 1 element on the page fails this check, rated critical by axe-core.

3 elements hidden from screen readers can still receive keyboard focus.

ARIA input fields must have an accessible name: 2 elements on the page fail this check, rated serious by axe-core.

Interactive controls must not be nested: 2 elements on the page fail this check, rated serious by axe-core.

ARIA toggle fields must have an accessible name: 1 element on the page fails this check, rated serious by axe-core.

48 images have no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 5 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

2 visible links have no text or label, so screen readers cannot say where they go.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Elements marked as presentational should be consistently ignored: 1 element on the page fails this check, rated minor by axe-core.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

Your meta description is 273 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image (also missing: og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://www.meanwell.com/sitemap.xml, so Google discovers your pages only by following links.

2 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 136 pages on meanwell.com and 34 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

Your homepage links to /catalog/Ebook/index.html, which answers with an error. Visitors hit a dead end and search engines drop it.

/, /productSeries.aspx and /productSeriesP.aspx all use the title “MEAN WELL Switching Power Supply Manufacturer”. Search engines can't tell which page to show for a search, so each competes with the others.

/about.aspx, /aboutFounder.aspx, /aboutRange.aspx, /aboutStory.aspx, /aboutVideo.aspx and /aboutEvents.aspx and 4 others use the same meta description. A description written for each page earns more clicks.

/serviceBusiness.aspx, /about.aspx, /aboutFounder.aspx, /productSeries.aspx, /aboutVideo.aspx and /aboutEvents.aspx and 3 others took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 39 found) and read each the way a search engine does.

10 of 45 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 (Not Found)”.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 139 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 8 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 12 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
